How do we reference the HeaderTemplate to specify the HTML using RenderFragment for the QuickGrid?

We have a .NET 8 & C# Blazor project in VS 2022 with a number of QuickGrids.

I want to place HTML and styling for the PropertyColumn's header text using the HeaderTemplate that will override the Title field. But I don't know how to use the HeaderTemplate.

My QuickGrid markup looks like this:

<PropertyColumn          Property="f => f.TXT_NAME"                       HeaderTemplate="<TemplateHeader>Missouri</TemplateHeader>"          Sortable="false" Class="itemName" />

I have googled and search for a sample of the correct way to specify/utilize the HeaderTemplate capability, but could not find any samples. What you see in my code above is a non-working GUESS of how to use the HeaderTemplate.

When I type the code for HeaderTemplate, VS 2022 immediately follows that with ="" -- implying some text should be typed in. BUT... I have tried various things and you can see my attempt at providing a component that contains a render fragment -- that will not compile with an error

An invalid expression term '<'

I am so stuck.

The render fragment component markup and code are as follows:

<div class="text-danger fst-italic fw-bold">   @ChildContent</div>@code {#pragma warning disable CS8618   [Parameter] public RenderFragment? ChildContent { get; set; }#pragma warning restore CS8618}

Your solutions, comments and questions are welcome.

Thanks.
